Speaker Specifications

Series
This is the manufacturer product line of speakers.
db (Polk)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Pair
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
6" x 9"
Design
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
3-way
Tweeter Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Dome
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

Silk-Polymer Composite
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Polymer/Mica Composite
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Butyl Rubber
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
300 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
100 watts
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
93 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
35 - 22000 Hz
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

No
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
3-3/16"
Bottom-Mount Depth
The depth when installed from the bottom of the mounting surface. Measured from the bottom of the speaker's magnet to the top of the mounting holes on the rim of the speaker.
3-3/4"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
8-1/2 x 5-3/4 
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
Yes
Number of Speakers
This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

Please refer to the product image and description for further details about the speaker.

Polk db 5.25" component speakers

August 31, 2009

These speakers have really clear sound quality and some pretty decent bass for component speakers. The only problem i had with them was the durability, the soldering that wired the diode to the positive connector was a little weak and broke on two of four of these speakers. But i should also mention that i was pretty rough on these when i first got them. But all four of them are holding up and kickin great after 6 months so far. And after these speakers i've sworn by polk audio ever since in the rest of my car audio purchases

Superior Sound Quality

January 6, 2014

I have finished installing a complete set of Polk speakers in my Town & Country van. (2) db691's in the back, (2) db691's in the doors, and (2) db521's in the dash. The sound is like a "Concert Hall" with the rich bass from the 691's, and the clarity and highs from the 521's. This is still coming from the standard "Head / Stereo" unit from the Town & Country. I have had several vehicles with "Premium" sound systems - but have not heard this kind of clear deep sound from any of them.
These speakers are the "BEST" value for the price.

If you are looking for the biggest, clearest, HiFi bang for your buck, you have to go for Polk Audio. I have db5251's (also available from SonicElectronics.com) in my front doors, the db691's in the rear deck, and a Polk db1222 subwoofer enclosure in the truck. I'm pushing 1600 watts RMS (100 watts into each db691) and the sound is amazing! Perfectly clear, excellent reproduction and imaging, outstanding HD HiFi that only Polk can produce for such a low price$.

I love this speakers they are playing together with a pair of Alpine SPR-69, they sound great, no problems with the combo. Bought those instead of a another pair of Alpines because they seem to have more bang for the money, but those sensitivity ratings are questionable the catalog only states 93db not db/m, so you never now what they really are.

Tweeters seem to be the hardest sound to find for me in a speaker, the tweeters in these speakers are awesome, I bought these because soft dome tweeters are my favorite and I have liked them the most. The speakers are very very loud and can handle some watts.

I had the Pioneer 5 ways 6x9s, and these are killing them no comparision, IMO. If you want loud speakers, that are crisp, with great highs, these are them

Excellent Speakers. They replaced the really old and very cheap factory units that were in my 1999 Mercury Villager Van. Don't laugh!! It is really a great small Mini Van. The sound and quality of there speakers are Excellent. I have owned a pair of them in a prior vehicle
and were very happy with the sound. You can really crank them up with NO distortion or that muddle sound in very low bass. Mid tone is very good the tweeters are Good not great. I do prefer SEPARATE Tweeters for that clear as a bell sound that gives you that dimension of space in the car.

Fantastic Speakers!

November 26, 2011

I bought these speakers to replace the factory front speakers in my 2003 Ram 1500. They sound great and are a huge improvement over the factory setup. (Note to Ram owners: these speakers are too deep to mount as is and will hit the window when it is rolled down, to fix this I used the grill spacer that comes with the speaker and put it on the back before screwing them in). I originally ran them off of head unit power but recently bought an amp (R400-4D) and it made a world of difference. The speakers sounded good off of head unit power alone but the addition of an amp really livened them up and increased bass response. Honestly my only complaint about these speakers is that they're a little too sharp on extremely high pitched sounds (think higher pitched cymbals, and the hissing "s" sound made when singing into a mic) and the speaker wire connections seem a little flimsy. Otherwise these speakers sound great and I highly recommend them.

Polk Audio db691

May 11, 2010

As of right now the 691's are the base and bass of my system. I have an MTX 704x giving them 70 watts of continuous power which to me is plenty. I've barely gone over halfway on the gain and they are more than loud enough. I'm getting a sub in a week which well help develop the low end because as of now I use a hpf on them so they don't bottom out. They're plenty enough though to keep the music playing loud especially if what you listen to is mostly rock, i can finish a song with them and have my ears ringing. They don't handle the deep end notes of rap music amazingly but what can you expect from a pair of speakers. Overall i've been very impressed with them.

Disappointing

December 5, 2012

After reading all the reviews and comparing these speakers to many others, I decided to buy. Hearing all the hype made me quite excited. I bought two pair (each door of my compass holds a 6x9). Eagerly awaiting the arrival of my speakers, I was happy thinking that I had found the perfect speaker. When I got my speakers, I couldn't be any more happy. Upon opening the box I couldn't help but notice how good they looked. They also appeared to be built really well, and the magnets where quite large.
After installing these, and hooking them up to my Polk PA660 amp (75rmsx4) I was even more happy. Talk about an upgrade over stock. After a week of break in, i decided to turn them up. The mids were good, and the highs sounded good. But the bass was lacking. Seemed to distort quite easy at all levels. No problem tho. That's what my subs are for. So I tuned my HPF to 60 hz. Still sounded like crap (so much for playing as low as 35hz) Then finally with it set to 80hz it sounded good. Minus no bass. At least the distortion was gone. By tuning out the bass it allowed the speaker to play the rest of the frequency's louder and cleaner.
All good right? Not really. They still seemed a little lacking and always left me wanting more. Eventually I kept wanting to turn them up more and more, yet still left unsatisfied. The vocals and highs, though clear and loud never seemed get the job done.
After a month of this things got worse. Down goes my first speaker. A few days later the second. With clean power and no distortion they shouldn't have blown on only 75rms (since rated at 100rms) I quickly contacted polk and got a new set. A month later and same problem Blown two more. Talk about upsetting.
So I tried to get another replacement. Decided on some Pioneers. Only 80rms, so less power, supposedly not as good of a brand as poineer, (told by friends and shops around the area) and a lot cheaper. I was just gonna use these a a cheap replacement until i could save up some substantial money and do more research and find a set off great speakers.
Well to my surprise, these pioneers were amazing. The highs were mind blowing and didn't seem lacking,the mids were great and finally i got some good bass. I know nothing beats a sub. But some times you don't always want to have the subs on. I was finally able to turn my amp back to full pass and have a good all around speaker. No more compromises and upsets like I had with the polks.
All in all these Polks are an OK speaker. But there are definitely better speakers out there that are cheaper, sound a lot cleaner, and have a better bass response. And to me Pioneer seems to be One of the better choices.

Great Speakers for the price.

August 15, 2012

I am huge Polk Audio fan to begin with, so my selection of Polk’s db691 for my car stereo upgrade was easy. They are clear, powerful and take the power without complaint. They were exact drop-in replacements for the rear deck of my 2000 Bonneville. With just a bit of research I was able to remove the rear seat and deck and install these in about two hours. I do think the sharp angle of my rear window does not aid in the transmission of the nice clean sound, but that is a GM, not Polk design "feature". My only suggestion for the folks at Polk Audio would be to include stake-on connectors with the speakers. The positive and negative are different sizes and a bit fragile. Having the exact match would reduce the likelihood of bending the terminals.

As always Sonic's price and service was top notch!

Excellent speakers for the price!

July 19, 2012

I bought these to pair up with the DB651's powered by an okay hand-me-down amp someone gave me that was, unfortunately, under-powering them. It wasn't until I hooked them up to a more appropriate powered Alpine amp powering them a lot closer to their RMS ratings that I was able to effectively break them in. For the most part, these speakers are definitely on the 'brighter' side. The highs turned out great, mids are good, however even under amplification there isn't too much mid bass happening with this series. But, pair them with a good sub and you'll have that gap remedied. All in all I'd say these are a great bang for your buck!

Installed these in the fron doors of my 2011 Maxiama with no difficulty. I had to remove a small plastic pin on the factory plate, but all screw holes lined up perfectly. Had to cut the factory harness and install spade ends as there is noo harness adaptor for this vehicle. Sound improvement is very dramatic with improved bass and clarity. Very good value at the Sonix price.

Awesome buy, won't purchase anything but Polk Speakers again!

August 19, 2011

They were easy to install, sound clean & clear even when they're turned up super loud and they're hard to hurt. I'm always jamming out in my car, and they've held up so far.

Superb and Well Balanced

March 25, 2011

The Polks are well balanced with good bass, great mids, and almost to much treble. The sound clarity sometimes makes me jump because the music sounds so real... I think what's that outside and it's actually the speaker producing quality sound. Speaker does need an amp if bass and VoLuMe is desired, otherwise these things almost sound like subs with superb SQ. Still the treble is a little to much when turned up, but can be tuned down. I strongly suggest this speaker to anyone looking for an awesome full range speaker. The only 6x9s that are better are competition series which cost much more. Excellent value!!

Sound Good, No Problems

February 1, 2011

The sound quality is very good and I haven't had any problems. I still need to add a subwoofer. The 6x9s don't quite deliver enough bass.

These are great speakers I have them powered by an old Sony XM 2200 GTX (can't believe it still works). I have them mounted in the back of my 87 jimmy and they sound really good and as far as marine use they do have some mud on them and still work so kudos to Polk on that. I for one hate the plastic grilles I have them installed for protection what little there is but the only company that I've seen with sleek grills is JL but there lower end just isn't worth it.

February 4, 2010

I thought these where very nice speakers for the price. Play very loud, loud enough were the tweeters start to hurt your ears. Occasionally they can make a little noticeable mirror shake and its only off of head unit power. Even while pounding on them hard haven't heard much bottoming out. Solid design, easy hook up and look pretty cool to.

These speakers have a silk dome tweeter which gives them a nice clear sound. They also have that added bass. I definitely recommend amplifying them up so one can fully appreciate them though.

Good Buy

January 5, 2009

Ive heard good things about Polk Audio but i was a little disappointed.
I have these in a '90 full size Blazer that came with no back speakers so i had to mount them in the siding in the back right between the front and back seats. The highs and mids sound amazing very clear, i have never heard any distortion form them. The lows don't work very well you can turn the bass up but nothing happens the woofer moves but i cant hear the bass. Its a good thing i bought these with a sub. I would recommend these to someone who was buying them that has a sub to take care of the bass and a head unit that has a high/low freq adjustment not to some one who is looking to change factory speakers

Pros: They look great and the highs and mids are amazing

Cons: Don't expect them to make bass sounds

So many decent reviews, I'm shocked. I put them in my sons car and his old beat up speakers sounded better, so we tried an amp and the screeching just got worse. Took them back and got the JL C2's that cost a few more bucks, WOW that was the best thing I ever did.

Put these in the rear of my 82 GMC restored pickup and along with the 5.25 polk component front speakers and an 800 watt pioneer amp I have a good clear sound without breaking the bank. Am considering a 10" subwoofer later when wife gets over the total cost of the restoration.

I Love the Polks

March 18, 2009

I installed a pair in the rear deck of my Mustang and the sound is awesome - plenty of highs and much more bass than I ever thought possible from just a pair of 6x9s. I have them hooked up to a Profile amp and they shake the whole car.

The guy that says he gets no bass from these in his blazer must have them hooked up out of phase (pos and neg backwards) because the bass from these is incredible - I've decided not to bother with a sub now that I got these.

I have only had a short while so can't speak as to the long term durability yet so I rate that part only 3 for "unsure".

What amp would work best with these?
Kyle K on Dec 5, 2014
Best Answer: Do you have another pair of speakers you want to run off the amp, or just these? If it is just these, look for a two channel amp with specs of 100 watts RMS at 4 ohms. If you are looking to get another pair of speakers, look for speakers with the same specs as these, and get a four channel amp.

Will these fit in the front doors of a 2011 Nissan Sentra? I know the spec's call for 6x9's but I do not know the depth tolerance.
john D on Nov 30, 2014
Best Answer: Hello John,

Unfortunately, the db691 will not fit the fronts' depth. The door has roughly 2.25"-2.5" of usable space. The most common solution, is to go with 6.5" Shallow Speakers for the front, utilizing the Scosche SA69 to fill in the space. The matching db Series is the Polk Audio db651s [2" Depth].
